.SH ENVIRONMENT VARIABLES
.IP DISPLAY
Use this X11 display. (see below)
.SH BUGS & CAVEATS
.B gdj
uses 
.B lrectwrite(3G)
and
.B rectzoom(3G)
to dump the pixmap to screen and to resize it when it needs to,
so limits on these functions will apply to
.B gdj
as well.
.PP
Some remarkable caveats are:
.TP
.B lrectwrite(3G)
doesn't work when you use X11 display thru sockets, so
.B gdj
won't work with non-local displays.
.TP
.B rectzoom(3G)
will scale images using integer factors on medium/low range workstations.
.TP
.B getmonitor(3G)
seems to return incorrect data, si gdj will restore always monitor
to HZ76 when using stereo modes.
